It Worked on My Machine, but Nobody Could Trigger It — Four Assumptions I Stripped Out of a Cowork Plugin

I bundled four working automation skills into a plugin and shared it. Only one of them ever fired. Here is how I measured skill trigger rate, and the four assumptions — vocabulary, paths, connections, and naming — I had to strip out before it was portable.

The Night a Connector Grew Write Tools, Your Unattended Job Could Quietly Send Something

The moment a connector update quietly adds write tools, a job you run unattended can suddenly send email or delete files. Here is how to build a gate that snapshots a connector's tool surface, diffs it, and stops unapproved writes before they run — drawn from indie development.

How Many Tasks Fire in the Same Minute — Flattening Cowork Scheduled-Task Collisions from Cron

When Cowork scheduled tasks bunch up at the same time and fight over shared resources, you can expand every cron expression into fire times, count collisions and true concurrency, and shave the peak with a greedy offset that never moves your premium slots. With working code and measured before/after numbers.

Let the Downstream Task Verify the Upstream Actually Ran Today: A Completion Ledger and Dependency Barrier for Unattended Schedulers

Unattended schedulers have no notion of dependencies, so when a morning data-refresh task fails silently, the noon generation task keeps running on yesterday's leftovers. This is a design for recording upstream completion atomically and having downstream assert its preconditions before running, with working TypeScript and lessons from my own operations.

Trusting a Three-Day-Old Mirror: Stopping Unattended Tasks from Acting on a Stale Working Copy

A persistent clone reused for speed quietly drifts from the remote. Read 'has this article been fixed yet?' from an out-of-sync tree and your unattended task duplicates work or 'succeeds' against an old world. Here is a HEAD-match plus writability preflight, with a self-healing re-clone, in bash.

Logged as success, but it produced nothing — stopping silent failures in Cowork scheduled tasks with end-of-run assertions

A Cowork scheduled task exits 0, yet not a single artifact was produced. Trusting the exit code alone hides this silent failure. Here is how to turn your definition of done into end-of-run assertions that fail loudly with an evidence log.

My Unattended Task Was Overwriting the Previous Day's Log — the Container's date Was Returning UTC

A Cowork scheduled task that wrote date-stamped logs was silently overwriting the prior day's file. The culprit was the container's date returning UTC. Here is how I isolated it and the permanent fix: pin the timezone, append instead of overwrite, and detect the failure.

Stopping an Unattended Writer From Publishing the Same Article Twice

When a Cowork scheduled task generates articles every day, the real danger isn't a crash — it's quietly publishing a piece that overlaps with one from a few days ago. Here is a gate that compares slug similarity and the day's log before publishing, built from a near-miss I caught this morning.
